• Use the inverse sine function

• Use the inverse cosine function

What should you check on your calculator before solving trigonometry problems?

• Battery level

• Degree mode

• Scientific notation

• Radian mode

If the hypotenuse of a triangle is reduced, what happens to the cosine of the angle?

• It becomes zero

• It increases

• It decreases

• It remains the same

What happens to the angle when the hypotenuse is shortened in a right triangle?

• The angle increases

• The angle becomes 90 degrees

• The angle decreases

• The angle remains the same
